CASEMENT-WINDOW STAY.

Application led March 28, 1918.

To all whom t may concern:

Be it known that I, Lnwls HANsoN, a,

sex and Province of Ontario, Canada, haveI invented a new and Improved CasementlVindow Stay, of which the following is a specification.

This invention relates to means for securing windows of the casement type in any desired open position, and its object is to provide a casement construction wherein the stay will be entirely concealed between the fixed and the swinging or opening frames of the casement when the window is closed.

This invention consists of aI casement window in which both the fixed and the movable frames are formedv of steel bars which are generally of channel form, both having legs or flanges of unequal widths, the narrow leg or flange of each contacting with the wider leg or flange of the other when the window is closed, in combination with a swivel bar pivoted on a pedestal which is mounted on the web of the fixed frame between the flanges thereof, the pedestal being of such height that the swivel bar may swing freely over the narrow flange on the fixed frame, and a slidably mounted second bar between the adjacent flanges of the movable frame, which bar is pivoted to the swivel bar. l It further consists in a guide for the sliding bar mounted between the flanges of the movable frame and providing means for locking the sliding bar. It also consists in the details of con struction illustrated in the accompanying drawing and particularly pointed out in the' claims.

In the accompanying drawing, Figure 1 is a bottom plan of this improved casement window when the stay is at the bottom and a plan thereof when the stay is at the top of the window opening. Figs. 2, 3 and l are sections on the lines 2 2, 3 3 and 4 4: of Fig. l, respectively. Fig. 5 is an elevation of a guide for the slide bar. Fig. 6 is an inside elevation of the bottom of the casement.

Similar reference characters refer to like parts throughout the several views.

The fixed frame of the casement ismade up of rolled bars, each substantially in the form of an I beam. The flanges of the side Specification of Letters Patent.

and top members will preferably be slightly narrower than those of the bottom members. The usual hinge connection 6 between the side bars 7 and 8 of the fixed and opening frames may be employed.

The bottom membei` of the fixed frame has a web 9 and inwardly extending flanges 10 and 11, the former much wider than the latter. The bottom member of the opening frame has a web 13, two flanges Hand 15 of which the former is wider than the latter, and a strip or rib 16 to support the glass.

A pedestal 17 is secured to the web 9 by means of screwslS, between the flanges 10 and 11, and receives a pivot .screw 19 that screws into one end of the swivel bar 20. Fig. 4 shows that this bar can swing over the Harige 11 and below the flange 15. A guide block 22 is secured to the lower member of the opening frame, being preferably inserted through a hole in the flange 15 and being held in position by screws 23 and 21. The slide bar 25 is movable longitudinally in this guide block, but may be locked in p0- sition by the screw' 26. An auxiliary guide 27 may be provided to steady the outer end of the slide bar 25. The swivel bar is connected to the slide bar by means of a pin 28 which may pass through the slot 29 in the auxiliary gulde 27.

The engagement of the flange 15 with the flange 10 and of the flange 14 with the flange 11 insures a tight joint between the two frames of the casement. The screw 26 is usually on the inner side of the opening frame, but the casement can be mounted s0 that the opening frame may swing in or out as may be preferred. When the window is closed, the pedestal 17, guides 22 and 27 and the bars 20 and 25 lwill be entirely inclosed by the flanges 10, 11, 14 and 15, and nothing but the screw 26 and the face of the block 22 will be seen. It will be readily seen that the stay may be placed at the top of the window as well as at the bottom. Bein concealed, the stay presents no objectiona le surfaces for the accumulation of dust.

The details of construction and proportions of parts may all be changed without departing from the spirit of this invention set forth in the following claims.-

1. In a casement window, the combination of a fixed frame and a movable frame hinged thereto, the fixed frame having inwardly extending flanges of unequal width and the movable frame having outwardly extending flanges of unequal width, all the flanges being parallel to the general plane of the window, the narrow flanges of each contacting with the wider flanges of the other.

2. In' a Casement window, the combination of a fixed frame and a movable frame hinged thereto, the fixed frame having in wardly extending flanges of unequal width and the movable frame having outwardly extending flanges of unequal width, all the flanges being parallel to the general plane of the window, the narrow flanges of each contacting with the wider flanges of the other, a pedestal mounted between the flanges of the lower bar of the fixed frame, a bar slidably mounted between the flanges of the lower bar of the movable frame, and a swivel bar pivoted to said pedestal and to one end of the slidable bar.

3. In a easement window, the combination of a fixed frame and a movable frame hinged thereto, a vertical pivot mounted on the lower member of the fixed frame between the sides thereof, a guide block secured to the bottom member of the movable frame, a bar slidable therein longitudinally of the bottom member, a swivel bar mounted at one end on said pivot, and a vertical pivot connecting the other end of the swivel bar to one end of the slide bar.

LL'In a Casement window, the combination of a fixed frame and a movable frame hinged thereto, a vertical pivot mounted on the lower member of the fixed frame between the sides thereof, a guide block secured to the bottom member of the movable frame, a bar slidable therein longitudinally of the bottom member, a swivel bar mounted at one end on said pivot, and a vertical pivot connecting the other end of the swivel bar to one end of the slide bar, and a set screw mounted in said guide block to engage the sliding bar to lock the movable frame in open position.

5. In a easement window, the combination of a fixed frame and a movable frame hinged thereto, the fixed frame having inwardly extending flanges of unequal width and the movable frame having outwardly extending flanges of unequal width, all the flanges being parallel to the general plane of the window, the narrow flanges of each contacting with the wider flanges of the other, a pedestal mounted between the flanges of the lower bar of the fixed frame, a bar slidably mounted between the flanges of the lower bar of the movable frame, and a swivel bar pivoted to said pedestal and to one end of the slidable bar, a guide for the slide bar mounted between the flanges of the lower bar of the movable frame, and means mounted on the guide to lock the slide bar in any desired position, a pair of bars, one connecting to the fixed frame and the other to the movable frame, and a pivot connecting the bars, said bars being inclosed between the flanges on said frames.
